The Standard & Poor’s 500 Index slid 0.4 percent to 1,283.32 at 9:33 a.m. in New York. The gauge has also dropped for six straight weeks, the longest retreat since July 2008. The Dow fell 58.70 points, or 0.5 percent, to 12,065.66. Its last six-week slump ended in October 2002, the start of a five-year bull market for the stock market.

“People are more anxious now,” said Mike Ryan, the New York-based chief investment strategist for UBS Wealth Management Americas, which oversees $761 billion. “Some people see these economic releases as signs that perhaps the economy is going to slip back into recession. Every time we get these economic weak spots, people are going to react a bit more harshly to it.”

Global stocks fell today after China reported a less-than- estimated $13.1 billion trade surplus in May, as surging imports signaled the nation’s demand may support global growth while adding pressure for higher interest rates. Stocks also fell after the Bank of Korea raised interest rates for a third time this year to rein in inflation that has exceeded its target range and curb record household debt.

Prices of goods imported into the U.S. unexpectedly rose in May as increasing costs for consumer goods like autos and clothing overshadowed the first drop in fuel expenses in eight months. The 0.2 percent increase in the import-price index, its eighth consecutive gain, followed a revised 2.1 percent climb in April, Labor Department figures showed. Economists projected a 0.7 percent decrease for last month, according to the median estimate in a Bloomberg News survey.

Benchmark gauges rose yesterday, snapping a six-day decline, as the U.S. trade deficit unexpectedly narrowed amid record exports and consumer confidence improved. Still, the S&P 500 dropped 5.5 percent since this year’s high on April 29 through yesterday amid weaker-than-expected economic reports.
